dhtmlxCombo fails to populate when in a custom form

Scheduler Javascript
#1

If I take my dhtmlxCombo out of the custom form it works fine, but fails to populate when in a custom form. Any ideas?

Custom Form

[code]












Engine Test:


[/code]

Lightbox

[code]scheduler.showLightbox = function(id){
var ev = scheduler.getEvent(id);
scheduler.startLightbox(id, html(“popup_form”) );

if (ev.requestor == undefined){ev.requestor = user;}		
html("requestor").value = ev.requestor;	

//Load engine test data.
var et = new dhtmlXCombo("enginetest","enginetest",200);

//THIS LINE DOESN'T POPULATE THE COMBO
et.loadXML("/" + dbScheduler + "/agEngineTests.xml?openagent");

}[/code]

XML DATA

[code]<?xml version="1.0" ?>

ET1 ET10 ET11 ET2 ET3 ET4 ET5 ET6 ET7 ET8 ET9 [/code]

It seems as if the combo is being populated correctly, but pops up behind the custom form and on selecting an option in the drop down it isn’t then shown in the combo on the custom form!

Any ideas?

Fixed the z-index and it all works now!

Hi
how to specify the z-index of the combo to fix this problem ?

.dhx_combo_list{ z-index:23000; /* z-index of combo-list */ }
